Aware about petrol pump?



Many of us are not aware that the petrol kiosk pump has a return pipe-line (in Pink ).. When the petrol tank (in the car) reaches full level, there is a mechanism to trigger off the pump latch and at the same time a return-valve is opened (at the top of the pump station) to allow excess petrol to flow back into the sump. But the returned petrol has already passed through the meter, meaning you are donating the petrol back to SHELL/CALTEX/MOBIL/ PETRONAS

Not sure whether this is true or not...just got it from other's blog..but it could be possible...
